Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
I am using STM32F103ZET6 to work with TI ADS8688 via SPI interface.Based on the sample program in STM32F10x_StdPeriph_Lib_V3.5.0 library, currently the basic function is OK, with SCK @ 9M.Here is my program screenshot about clock and SPI configurati...
I'm using a NUCLEO-H743ZI2 board and following the examples in Ux_Device_CDC_ACM targeting H723 and Ux_Device_HID_CDC_ACM targeting H747, but no data ever comes in and fails to match the "ux_utility_memory_compare" function in "usbx_cdc_acm_read_thre...
Could someone tell me, what i do wrong?I made an external bootloader on QuadSPI chip and it works well with applications that do not use a FreeRTOS!But, I need to make the application that use FreeRTOS and it is don't work properly! The steps that I ...
Hello!I'm trying to create a USB composite device with 2 registered classes DFU and CDC ACM, using USBX middleware on stm32u585 mcu.I was going through those two examples on git:STM32CubeU5/Projects/B-U585I-IOT02A/Applications/USBX/Ux_Device_DFU/STM3...
I have had an sdmmc card running fine using STMCUBE MX with the default pins PC9,PC10,PC11,PC12,PD2 and PB13 with the SDCARDCARD DETECT PIN being allocated to a free GPIO Input (PC8) but when I reallocate the pins to free up the ULPI interface - prim...
I would like, if possible to use the 64 pin package in my design. The problem is that I need a CAN bus and would like to program the chip straight from USB (with potentially needed level shifting?) with the DFU I've heard so much about. I can move CA...
I am trying to configure the STM32L476 as a USB Microphone, my input is an analogue microphone through the ADC. I configure the device as an Audio class, at first my computer found it as a speaker, so I search about it and find that I need to redefin...

I am using multiple devices which access I2C communication channel. Can anyone suggest me what should be the preferred method to avoid clashes between the devices.The devices are placed across different RTOS tasks.
Posted on November 10, 2014 at 14:30Hello. I am using the new HAL library for writing a program for STM32F4Discovery (for university presentation). The program activates a USB FS CDC device once running to speak with a PC. I've attached an SD card s...
